3 Claims, 1 Drawing Figure DEVICE FOR STITCHED-WIRING F LONG-TIME MEMORY MEANS The present invention relates to computing machincry, and more particularly to devices for effecting stitched-wiring processes for the creation of long-time memory means, and may be used for creating bundletype long-time memory means.

Known in the art are devices for stitched-wiring of long-time memory means, whose operation is based on a consecutive performance of two alternate motions: that of cores of long-time memory means arranged on the surface of a tum-table along a circumference concentric to its axis of rotation, and that of a means adapted to place code wires transversely to the movement of the cores in accordance with a preset prograin.

The turn-table is provided with a drive for turning it intermittently through a pitch equal to the spacing of the cores along the circumference of the tum-table. For a precise stoppage of the tum-table after it has completed its turn, provision is made of a unit for fixing the tum-table in position,which is geared with said drive. The number of points at which the position of the turn-table is thus fixed is equal to the number of cores arranged on the tum-table.

Arranged above the surface of the tum-table on which the cores are disposed is a means for placing code wires. Said means is a-tubular needle which passes a code wire. Provision is made of electromagnets which move said means radially to the tum-table.

Fixed over the periphery of thetum-table are contact groups, their number being equal to that of the cores arranged on the tum-table. Each of said contact groups is associated with respective outputs of a program setting unit, and brushes of said contact groups, via a cam switching arrangement, are associated with corresponding electromagnets which move said means adapted to place code wires.

The above-described device operates as follows.

The program setting unit through the cam distributing arrangement actuates the drive of the tum-table. The tum-table with cores arranged thereon turns through an angle corresponding to a pitch with which the cores are spaced.

Then the fixing unit comes into operation and fixes the table in said position. Then the cam distributing arrangement through the brushes and contact groups actuates appropriate electromagnets, and the latter move the means for placing code wires in a required direction radially to the table, and a given core is thus threaded or stitch-wired with a code wire.

After that the fixing unit releases the tum-table, and the latter is again turned by the drive through a required angle in the same direction. The sequence of operations of all the mechanisms is repeated till all the cores arranged on the tum-table are stitch-wired.

However, the known devices for stitched-wiring of long-time memory devices are not free from essential disadvantages.

The stitched-wiring process is performed with periodic startings and stoppages of the driving means of the tum-table, fixing unit and electromagnets, and therefore the operation of the entire device is associated with frequent startings and stoppings thereof.

This involves undesirable inertia loads and adversely affects the dependability of the device. Moreover, such a mode of operation imposes limitations on the speed of stitched-wiring of cores of long-time memory means.

Non-synchronism in the operation of the electrical control equipment and inertia of the actuating mechanisms (drives) necessitate the provision of a special mechanism for a precise fixing of the tum-table, after it has completed its turn, relative to the means that threads code wires through the cores, so as to obviate possible damage of said cores arranged on said table at the moment said means is moved relative to said cores. in case the number of said cores is great, a great number of contact groups and brushes is required accordingly. All these factors make the entire device complicated and impair its reliability.

It is an object of the present invention to eliminate the above-mentioned disadvantages.

The specific object of the invention is to provide a device for stitched-wiring of long-time memory means according to a pre-set program, which would be reliable in operation, feature high speed, and be simple in design.

Said specific object is accomplished by a device for stitched-wiring of long-time memory means, wherein a means for placing code wires with respect to cores is associated with a mechanism that controls said means and deflects it in accordance with a pre-set program. According to the invention, the mechanism controlling the deflection of the code wire placing means comprises: a driven carriage travelling along guides over a row of cores and mounting said means, associated through a lever with a drive for deflecting said means transversely to the row of said cores, and a mechanism for synchronizing the deflection of the core wire placing means relative to the spacing pitch of said cores in a row, the mechanism being associated with said drive and said means by the above-mentioned lever and kinematically associated with a drive of said carriage, one end of said lever being rigidly connected with said means, and the other end of said lever being operatively associated with said synchronizing mechanism.

It is expedient that the above-mentioned mechanism for synchronizing the deflection of the code wire placing means be made as a rotary drum, having a rotation period proportional to the pitch with which cores are spaced in a row, the drum being provided with at least one groove, whose length corresponds to the space between two adjacent cores in a row, said lever on an arm operatively associated with the drum having a pin which periodically interacts with said groove under the action of the deflection drive, thus ensuring placing of a code wire between the cores in accordance with a preset program.

The drive for deflecting the code wire placing means, adapted for placing code wires in accordance with a pre-set program, may be made as an electromagnet with an armature articulated to a lever, and a return spring which associates said means with the carriage.

The present invention will become more fully apparent from a consideration of a detailed description of an exemplary embodiment thereof, to be had in conjunction with the accompanying drawing, wherein the device of the invention for stitched-wiring of long-time memory means according to a pre-set program is shown diagrammatically.

The present device comprises a carriage l on which a means 2 is movably mounted which is adapted to place code wires 3 and comprises a tubular needle 4 and a reel 5 on which wire 6 is wound. On a stationary table 7 of the device under the tubular needle 4 cores 8 of a long-time memory means 9 are arranged in rows. The carriage 1 can travel along guides 10 over a row of the cores 8, and said means 2 fitted on an axle 11 may deflect transversely to a row of the cores 8.

The carriage 1 is moved along the guides 10 with the help of a drive 12 with a lead screw 13.

For deflecting said means 2, fixed on the carriage 1 is a deflecting mechanism which consists of an electromagnet 14 with a pullable armature 15 and a return spring 16 that associates the tubular needle 4 with the carriage 1 and retains the means 2 in its initial position.

Kinematically associatedwith the drive 12 of the carriage 1 is a mechanism for synchronizing the deflection of the means 2 for placing the code wires 3 with the space pitch of the cores 8 in a row, said synthronizing mechanism comprising a rotary drum 17 provided with at least one groove 18 on its surface 19.

A drive shaft 20 through a gear train 21 is rotated by the lead screw 13, this rotation being matched with the travel of the carriage 1 that mounts the means 2 for placing the code wires 3. The means 2 for placing the code wires 3 interacts with the deflection drive and with the synchronizing mechanism by the intermediary of a lever 22 whose one end is rigidly fixed on said means 2. The other end of the lever 22 is articulated with the armature 15 of the electromagnet 14 of the deflection drive and is' provided with a pin 23 adapted to interact with the grooves 18 of the rotary drum 17 of the synchronizing mechanism.

The period of rotation of said drum 17 and the pitch with which the grooves 18 are arranged on the cylindrical surface 19 of the drum are proportional to the pitch with which the cores 8 are arranged in a row, and the length of the groove 18 corresponds to the space between the cores 8 in a row.

Fixed on a bed 24 of the entire device are guides 25 with a drive 26, for moving the carriage 1 with the means 2 for placing the code wires 3 into the second, third, etc., rows of the cores 8, and with a lead screw 27.

The drive 12 together with the drive 26 for moving the carriage and with the electromagnet 14 of the deflection drive are electrically associated with a program setting unit 28.

The present device for stitched-wiring of long-time memory means operates as follows.

The drive 12 is actuated by a signal produced by the program setting unit 28 and by rotating the lead screw 13 causes the carriage l to move at a constant speed along the guides 10 over a row of the cores 8 of the long-time memory means 9. Simultaneously the gear train 21 brings into rotation the drive shaft 20 and the rotary drum 17 of the synchronizing mechanism.

As the carriage 1 moves longitudinally to the row of the cores 8, signals sent by the program setting unit 28 actuate the electromagnet 14 of the deflection drive somewhat in advance. The armature 15 tends to deflect the lever 22 and, together therewith, the means 2 for placing the code wires 3 from the initial position. The pin 23 of the lever 22, thrusting against the cylindrical surface 19 of the drum 17, opposes this motion, till the groove 18 is found to match the pin 23.

against the pin 23 correspond to the positions of the tubular needle 4 between the adjacent cores 8. It is just at such moments that the tubular needle 4 is deflected.

The fact, that control signals are sent by the program setting unit 28 somewhat in advance does not cause any troubles in the operation of the means 2 for placing the code wires 3, since the zone within which said means 2 deflects while moving along a row of the cores 8 is.

limited by the length of the groove 18 and is equal to the space between adjacent cores 8.

At the same time, the sending of the control signals in advance precludes those adverse efiects which might influence the proper operation of the device due to non-synchronism in the performance of the electrical control equipment.

In this way one row of the cores 8 is stitched-wired with the code wire 3.

By a signal sent by the program setting unit 28 the drive 26 is actuated adapted to move the carriage l, and, through the intermediary of the lead screw 27 the means 2 for placing the code wires 3 is brought over to a subsequent row of the cores 8, etc- The stitched-wiring of the subsequent rows of the cores is performed by following the procedure 7 described above.

The herein-disclosed device oflers essential advantages over the device known heretofore.

Due to the fact that the present device performs stitched-wiring of cores of long-time memory means by virtue of a uniform movement at a constant speed, the origination of adverse inertia loads associated with frequent startings and stoppings of the drives is precluded, the operation of the device becomes more reliable, and the high speed thereof is increased.

The use of the synchronizing mechanism of the above-described design makes it possible to send control signals to the drive responsible for the deflection of code wire placing means in advance, thereby obviating those adverse effects which otherwise interfere with the proper operation of the device, being caused by nonsynchronous operation of the electrical control equipment; in the present device proper deflection of said means between adjacent cores in a row is adequately ensured. This enhances the stability and dependability of the device operation and precludes damages to the cores to be incurred during the placing of code wires.

The present device combines the above-mentioned advantageous features with simplicity of its design.
